LUBRICATOR.

SPECIFICATION forming part of Letters Patent N o. 476,253, dated June7,1892. Application tiled September 2l, 1891. Serial No. 405,329. (Nomodel.)

To all whom, it' may concern:

Be it known that we, WALLACE B. CURTIS and EUGENE LONG, citizens of theUnited States, residing at Pomeroy, in the county of Meigs and State ofOhio, have invented certain new and useful Improvements in Means forCleaning and Lubricating Sprocket-Chains; and We do hereby declare thatthe following is `a full, clear, and exact description of the sam e,

reference being had to the annexed drawings, making a part of thisspecification,l and to the letters of reference marked thereon.

This invention has for its object to provide a simple and cheap yetdurable and efiicient means for cleanin g and lubricating thesprooket-chain on any and all chain machinery, and While it is designed,primarily, for use upon bicycles and is so shown it is not intended torestrict the invention to such use. We provide a carrier in which abrush is rotatably held, the brush having a chambered hub in which isdesigned to be held the lubricant and through perforations in which itgradually shifts upon the chain. An agitator is usually provided withinthe chambered hub to prevent clogging of the perforations. Suitablemeans are provided for regulating the discharge of the lubricant.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a partof thisspecification, and in Which- Figure l is a side elevation of a portionof a bicycle, showing our attachment applied thereto. Fig. 2 is aperspective view of the attachment removed. Fig. 3 is a central verticalsection through the brush. Fig. l is a perspective view of the damperremoved. Fig. 5 is a like view of the knocker or agitator removed.

Like letters of'reference indicate like parts throughout the severalviews in which they occur.

Referring now to the details of the drawings by letter, A designates thesprocket-chain to be lubricated, Which in this instance is shown as thatof a bicycle of known construction, B

being the horizontal portion of the frame, C the sprocket-Wheels, and Dthe mud-guard. Our device is intended to be so arranged that it willdeposit the lubricant upon the chain. It may be located at any desiredplace. It may deposit the lubricant upon the chain either upon theupperor lower portion thereof. Vhen designed for bicycles, it has beenour practice to support the device in the manner shown in theaccompanying drawings; but it is evident that the manner of supportingthe device Will depend upon the nature of the machine upon which or inconnection with Which it is to be employed. So far as the successfuloperation of the device is concerned, it is necessary only that thebrush be so supported as to readily revolve in suitable bearlngs.

' In the construction shown, E is a clamp,

vvith spring-arms, Which are curved at their free ends to embrace thehorizontal portion of the frame, the inner faces of the said curved endsbeing provided with a lining of felt or analogous material when desiredto prevent marringof the frame. The clamp is provided with a set-screw efor tightening the same upon the frame. Supported by the said clamp andextending substantially horizontally is the support F, which in thisinstance is formed of Wire, with a loopf, carrying the spring-armsf,which form bearings for the pintles of the brush, the brush beingarranged Within the said loop, as is shown in Fig. 2.

The prime novelty resides in the brush and its component parts. Thisbrush Iconsists of a cylinder G, which is provided with a plurality ofperfor-ations g, which may be of any desired size, shape, and number,and secured in this cylinder are the bristles or'fibers of the brush.The cylinder and brush may be of any suitable materialv and of a sizecommensurate with the Work required of it. It desired, the cylinder mayhave a metallic lining H, Which should also be provided Withperforations @corresponding to those of the cylinder. One end isprovided With a head G', provided centrally upon its outer face with aheaded pin g', which serves as the pin-` tle on which it revolves, andat the other end is provided a removable head H', carrying a similar pinh', serving as the other pintle-,the

IOO

said head being removably held in position in any suitable manner-as,for instance, by being screw-threaded, as shown in Fig. 3.

I is a knocker or agitator, which may be of any suitable shape,preferably that shown in Fig. 5, and this knocker is designed to beplaced Within the cylinder to agitate the lubricant and prevent cloggingof the perforations.

J is a cylinder provided with a plurality of longitudinal slots j and athumb-piece j', as seen in Fig. 4. This cylinder is designed to beplaced Within the cylinder and serves as a damper for regulating thedischarge of the lubricant. h

In practice the brush is suitably supported so that its periphery willrevolve in close proximity to or in contact with the chain to belubricated. as seen in Fig. 1, it iirst having been filled With graphiteor other preferred lubricant, and as the brush revolves by reason of itscontactwith the moving chain the lubricant is sifted down through theperforations and through 'the bristles on the chain, the sifting beingregulated by the damper,

sisting of a perforated cylinder having a removable head, a revolubleslotted damper, and a knocker, as set forth.

2. A rotatable lubricator consisting of a perforated cylinder havingheads, one of which is removable and both carrying `pintles, and a splitrevoluble spring-damper provided with a thumb-piece, as set forth.

In testimony that We claim the above Wer have hereunto subscribed ournames in the presence of two Witnesses.
